A 12-ohm resistor is connected in series with a 23-ohm resistor. They are placed across a 120-volt power source. What is the current in the circuit? A) 35 amps

B) 10 amps

C) 5.2 amps

D) 3.4 amps

3.43 A

Explanation:

Applying,

V = IR' Equation 1

Where V = Voltage, I = current, R' = Total resistance

Make I the subject of the equation

I = V/R' Equation 2

From the question

Given: V = 120 volt, R' = (12+23) = 35 0hm

Substitute these values into equation 2

I = 120/35

I = 3.43 A

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
